Description

High stability injection molding machine

Technical Field

The invention relates to the technical field of injection molding machines, in particular to a high-stability injection molding machine.

Background

Plastics are high molecular compounds, commonly called plastics or resins, which are made from monomers by polyaddition or polycondensation, can freely change the components and shape and form, and are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, pigments, etc. The main component of the plastic is resin. The term resin is originally named from lipids secreted from animals and plants, such as rosin and shellac, and refers to a high molecular compound that has not been mixed with various additives. The resin accounts for about 40-100% of the total weight of the plastic. The basic properties of plastics are largely determined by the nature of the resin, but additives also play an important role. Some plastics consist essentially of synthetic resins, with no or little additives, such as plexiglas, polystyrene, etc. Plastic products are widely used in life.
